Question

(c) How does the digestive system work?​

Answer 1

Answer:

The human digestive system is a sequence of organs that use mechanical and chemical means to take in food, break it down, extract nutrients and energy, and eject waste products in the form of urine and feces. This system evolved incrementally over the course of hundreds of millions of years and is the only natural way for humans to obtain energy for movement and thinking. It is capable of handling a variety of food sources, both animal and vegetable, but tends to handle food best when it is cooked. Because cooked food has been around for so long, humanity as a species is slightly “spoiled” in its favor, and many people get sick if they consume food that has not received adequate cooking.
